  • Olefin metathesis catalysts
    Patent number: 10265691
    Abstract: The present invention refers to novel ruthenium-based catalysts for olefin metathesis reactions, particularly to fast initiating catalysts having stereoselective properties. In olefin metathesis reactions, the disclosed catalysts provide a high catalytic activity combined with the capability to generate higher yields of the olefin metathesis product.
    Type: Grant
    Filed: July 8, 2016
    Date of Patent: April 23, 2019
    Assignee: Bergen Teknologioverforing AS
    Inventors: Vidar R. Jensen, Giovanni Occhipinti

  • Organometallic catalysts
    Patent number: 9795953
    Abstract: The present invention refers to novel ruthenium- and osmium-based catalysts for olefin metathesis reactions, particularly to catalysts having stereoselective properties. Z-selectivity is obtained by utilizing two mono-anionic ligands of very different steric requirement. In olefin metathesis reactions these catalysts selectively provide the Z-isomer of disubstituted olefinic products even in presence of air or of acids.
